UNITED STATES PATENT OFFICE.

LESLIE R. N. (JARVALHO, 0F TOLEDO, OHIO, ASSIGNOR TO THE CLOSURE SERVICE COMPANY, OF TOLEDO, 0HIO,A CORPORATION OF OHIO.

RECEPTAOLE CLOSURE.

Application filed July 5, 1923.

My invention relates to a receptacle closure or cap adapted for use with bottles, jars or other containers. More particularly, it relates to a type of closure comprising a detachable portion which serves to secure the closure in sealing position. In order to remove the cap from the container the first time, said detachable portion is torn oh and discarded, after which the cap may be used as a temporary closure.

As herein shown, the cap comprises a cover portion and a flange portion. The flange is scored adjacent its lower edge to form a detachable attaching strip which serves as a means for securing the cap to the container.

In my co-pending application, Serial Number 511,392, filed October 29, 1921, I have shown a closure with an attaching strip of the character above indicated, having one end extended to form a tongue or finger-piece which may be grasped for ripping oft the attaching strip.

An object of the present invention is to provide an improved form of attaching strip in which the flnger-piece extension is omitted, thereby avoiding the objections incident to a finger-piece projecting beyond or overlying the body of the cap, and also resulting in a substantial saving in the sheet metal from which the cap is formed. The attaching strip is preferably formed with a bead or hollow rib extending lengthwise thereof, and provides a means for engagement of a tool for ripping oil the attaching strip.

Other objects of the invention will appear hereinafter.

In the accompanying drawings:

Figure l is a part sectional elevation of a container and closure cap, constructed in accordance with my invention.

Figure 2 is a section at the line IIII on Figure 1.

Figure 3 is a view showing the method of using a tool for ripping oil the attaching strip.

The closure or cap comprises a cover piece 5 and a flange portion or skirt 6 attached thereto by means of a bead 7. The container to which the cap is applied is here shown as a bottle 8, having a neck provided with a shoulder 9. The lower edge 10 of the cap .is bent inwardly beneath the shoulder 9 to hold the cap in sealing position. A gasket 11 may he used to form a tight seal.

The flange portion 6 of the cap may be Serial No. 649,577.

made of a strip of sheet metal bent to cylindrical form and having its edges overlapped and connected by a seam 13. A removable strip 14 at the lower edge of the flange 6 is provided by scoring the flange along a. line 15 extending circumferentially ot the cap. The attaching strip .14. is formed with a hollow rib or head 16, extending lengthwise thereof. Although this bead is herein shown as extending the entire length of the removable strip, it may, if desired, be much shorter. The head provides a space between the cap and. the neck of the bottle, permitting any pointed tool, as for example, the tine of a fork 17, to be inserted for tearing off said strip.

As shown in Figure 1, the flange portion 6 is cut away at the lower end of the seam 13 to provide a space 18 between the ends of the strip 14. This facilitates the use of the tool 17. If desired, the strip 14 may also be cut away at an additional point or points 19 (Fig. 2). Formation of the two open points permits removal of a portion of the strip at a time and consequent elimination of difliculties experienced where a part of the strip tears away before it has performed its function.

lVhen it is desired to remove the cap from the container, the fork tine, or other implement, is inserted beneath the bead 16 at the opening 18 (or 19) and the strip 14 ripped off by a movement of the tool lengthwise of said strip. After the tearing off of the strip has been started by the tool, the end 20 may, if desired, be grasped by the fingers and the strip readily removed.

Modifications may be resorted to within the spirit and scope of my invention.

What I claim is:

1. A closure comprising a cover portion and a skirt or flange, said flange being circumferentially scored adjacent its lower edge to provide a removable strip comprising that portion of the flange between the score and bottom edge of the flange, said strip being formed with a hollow bead extending lengthwise thereof and shaped to permit the insertion of a tool between the strip and the container to which the closure is applied.

2. A closure comprising a cover portion and a skirt or flange, said flange being circumferentially scored adjacent its lower edge to provide removable strip comprising that portion of the flange between the score and lOO bottom edge of the flange, said strip being shaped to permit the insertion of a tool between said strip and the container to which the cap is applied.

3. A closure comprising a cover portion and a shirt or flange, said flange being circnn'iiferentially scored to provide a removable strip comprising that portion of the flange between the score and bottom edge of the flange, said strip comprising a hollow convex projection or head extending lengthwise thereof and presenting an end opening for the ins -rtion of a tool between the bead and the container to which the closure is applied.

at. A closure comprising, in combination, a cover portion and a flangeportion connected thereto'by a seam, said flange portion comprising a sheet metal st 'ip'bent to cylindrical -ii'orm and having its ends connected by a seam, said flange portion being scored ci cuinit'erentially adjacent its lower edge to provide a removable attaching strip, said strip being cut away at one point in its periphery'to permit insertion of a tool between said strip and the container to which the cap is applied. 7 Q
